Is it possible to run inherited methods in the scope of the child class?
In my case I have an abstract class called 'Company' and some child
classes. There is a non abstract function in 'Company' which prints
'$this->phoneList'. That function should be the same to all child
classes, without rewritting it in every class.
I call the printing method via the child class like
$childObject->printPhoneList();
The call seems to be handed over to the parent class 'Company' which is
fine. But the $this points to the phoneList of the abstract parent
class. So the phoneList in the abstract class seems to be unset, since i
have set the phone list in the child class.
Here's a short example, showing what I mean:
<?php
abstract class AbstractClass {
^ seeing as you are using the abstract keyword you must be using php5.
which supports the 'parent' keyword but that is not what you want right now...
private $var;
get rid of the 'private' here and replace it with 'protected'
public function printVar() {
echo('var: ' . $this->var . '<br>');
}
}
class ConcreteClass extends AbstractClass {
public function __construct($var) {
$this->var = $var;
}
public function printVarChild() {
echo('var (child): ' . $this->var . '<br>');
}
}
$cl = new ConcreteClass(15);
$cl->printVar();
$cl->printVarChild();
?>
Output is:
var:
var (child): 15
Has anyone an idea how to print the $var of the child, without copying
the method in every child class?
thanks in advance,
Norbert
